SAMUEL GOULDEN, OF NEWVARK, NEIV JERSEY.

COMBINED QOOR-FASTENER AND ALARM.

SPECIFICATION forming part of Letters Patent No. 404,617, dated June 4, 1889.

Application filed February 23, 1889. Serial No. 300,938- (No model.)

To all whom it may concern:

Be it known that I, SAMUEL GOULDEN, a subject of the Queen of Great Britain, residing at Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Door or Window Fasteners and Alarms, of which the following is a.

specification, reference being bad therein to the accompanying drawings.

This improvement relates to that class of door and window fasteners which are combined with a cap-discharging device which operates when an attempt is made to open the door or window from the outside; and the invention consists in the peculiar construction, arrangement, and combination of parts hereinafter more particularly described, and then definitely pointed out in the claims.

In the accompanying drawings, Figure 1 represents a perspective view of my device in position for use; Fig. 2, a back view with the hammer set ready to fire a cap; Fig. 3, a longitudinal section also with the hammer set; Fig. 4, a similar section with the hammer down after discharging the cap.

Referring now to the details of construction,A represents a stiff metallic plate whose from will clearly be seen in Fig. 2, over which is a slide, B, preferably made of sheet metal, having its edges 0 C bent over the sides of the plate A, as shown in Fig. 2.

At D D are shown two cars formed out of the metal taken from a slot E in the slide B, in which are formed holes to receive the pivot 5 F of a hammer G, which has a head H and toe I, the latter being widened for a purpose hereinafter explained.

K- indicates a spring,the free end of which acts on the toe I, while the other end passes through a slot E and into a second slot 6 and under a cup L, secured to the top of the slide by riveting, soldering, or otherwise.

When the fastener is to be, used, it is set corners to of the plate A, and as the motion of the slide continues the toe I is pushed backward until it passes from under the pivot of the hammer, when the spring begins to act upon it and the hammer falls, thus exploding the cap and alarming the sleeper. This, however, is not all of the function of the device, for as soon as the slide has tripped the hammer and exploded the cap the point or the upper end of the plate A comes into play and catches, into the door and thus becomes a resistance-bar, receiving andresisting the whole of the pressure and forming a perfect door-fastener, which renders it impossible to open the door from the outside.

My improvement can be used with equally good effect as a window-fastener by resting the lower part on the top of the lower sash and pressing the point of the plate A against a bar or stile of the upper sash, when any attempt to move either sash will explode the cap, as before described, and will also firmly secure the sash from being opened.

From the above it will be seen that my fastener and alarm will not only thoroughly alarm a sleeping occupant of the room and form a perfect fastener, but is cheaply and easily made, is very durable, not likely to get out of order, and is so portable that it may be carried in the vest-pocket.

It is obvious that instead of the paper cap an ordinary gun-cap can be set on the head of the hammer, which will be exploded as the hammer falls. If this be done, the cup may be dispensed with.

IVhat I claim as new is- 1. The combination, with the plate or resisting-bar A and slide B, moving parallel therewith, of a hammer carried by one of said instruments and tripped by the other, and a spring for operating the hammer, substantially as described.

2. The combination of the plate A, slide B, embracing said plate and moving parallel therewith, the hammer mounted on said slide, and a spring attached to said slide for operating the hammer, substantially as described.

3. The combination, with the perforated plate A, the slide 13, having its edges turned presence of two witnesses, this 20th day of over the sides of the plate A,and ears formed February, .1889.

on the face of said slide, of a hammer w i 1 r l 4 T 4 mounted 111 851-10. cars, a spring acting on the in URL LDLN 5 hammer and attached to the slide, and a cup \Vitncsses: V

to receive a cap, substantially as described. PHILEMON \VOODRUFF,

In testimony whereof I alfix my signature, in \VILL O. HEADLEY.
